ELECTBIGAL HEATER.

To all whom it may concern:

' 'One of the objects of the invention is to provide a heater of the parabolic type,

having means whereby it may be attached to and supported by a standard electric lamp socket. A further object is to pro vide means whereby the parts may be relatively adjusted to bring the heat unit and the reflector into focus.

The invention will be hereinafter fully set forth and particularly pointed out in the Figure 1 is a side elevation, partly in section, illustrating a heater constructed in accordance with the invention. Figure 2 is a top plan view of the reflector, illustrating means for attaching the same to a lamp socket. Figure 3 is a side elevation, illustrating a slight modification. Figure 4 is a side elevation, illustrating a second modification.v Figure 5 is a view illustrating a method of supporting a plurality of heaters. v Referring to Figures 1 and 2, 1O desiga of any standard construction.

na'tes an electric lamp socket, which may be The reflector 11, is of the well-known paraboli'c'type providedfwith a central opening 12, and

aving attached to it in' register with said 0 nihg, a split collar 13, provided with a camping screw 14. The split collar 13, may be attached tov the reflector 11 in any des red manner, the drawing illustrating the parts as connected by rivets. The heating unit 15, is of a tv commonly employed in electric heaters being constructed of an approximately cylindrical body of insulating material, provided with a wrap ing of resistance material, one end of said unit being provided with a threaded plug-like portion 16, shaped to engage'the threaded shell The heat unit is rovided with a central contact 18 and a shell contact 19, similar to the contact employed in the standard plugs used inconnection with lamp sockets.

In practice, the reflector. 11 is first attached to the lamp socket 10, by means of the split sleeve 13. The'heat unit 15 is then passed through the. opening 12, and screwed into the threaded shell 17 of the lamp socket. The split sleeve 13 permits of an adjustment of the reflector 11, longitudinally of the shell of the lamp socket 10, to bring the reflector into focus with the heatingunit, the clamp screw. 14, being tighterred when the proper adjustment is obtamed, so as to retain the reflector in it adjusted position. I

Inlieu of employing the split ring 13, the reflector ,11- may be provided with a flanged sleeve 20, shaped to fit within a standard shade ring 21, of a type commonly attached to standard lamp sockets, the re flector being supported by screws 22, carried b the shade ring in a well-known manner. ee Figure' In the form of the invention illustrated in Figure 4, a socket 25 is provided, having a flange 26, secured to the heat reflector 27, said socket having a threaded portion capable of receiving ,a com lemental portion 28,

of a heating unit 29. he upper end of the heating unit 29 is formed as a plug 30, capable of engaging the threaded shell of the ordlnary standard lamp socket, suitable means bein provided to complete the circuit 'be readily understood that a simple and in expensive form of heater of the parabolic type is provided, the same having means whereby the parts may-be attached to and supported by a standard lamp socket, thereby avoiding the necessity of employing standards or ,other supports.

Having thus explained the nature of the invention and described an operative manner of constructing and using the same.

although without attempting to set forth all of the forms in which it may be made, or

all of the forms is 1. heater of the character described comprising a parabolic reflector, a heating unlt, and means whereby both may be'connected to and supported by a standard lamp socket. I

2. A heater of the character described comprising a parabolic reflector, and a heati nit having means at one end whereby it may be electrically connected with a standard lamp'socket.

3. A heater of the character described comprising a parabolic reflector, a heating unit having means at one end whereby it may be electrically connected to and supported by a standard lamp socket, and means whereby said reflector and said heating unit may be held in juxtaposition with each other.

4. A heater of the character described comprising a parabolic reflector an approximately cylindrical support member, and a heating element carried thereby, said support member being adjustable relative to the reflector, whereby the heating element may be brought to proper focal position.

5. A heater of the character described comprising a parabolic reflector having a split sleeve capable of engaging a standard lamp socket, and a heating unit having of its use, what is claimed means whereby it maybe electrically con nected with said socket in juxtaposition with said reflector.

' 64 1 heater of the character described comprising a parabolic reflector having a sleeve, and a heating unit extended longitudinally through said sleeve, and having means whereby it may be electrically connected with astandard lamp socket.

71 A .heater of the character described comprising a parabolic reflector having a sleeve, a heating unit screwed within said sleeve and having means whereby it may be electrically connected with a standard lamp socket.

proximately cylindrical heating unit having its axis coincident with the axis of said reflector. v

9. A heater of the character described comprising an approximately cylindrical heating unit having means at one end where by it may be electrically connected with a socket, and a parabolic reflector in juxtaposition with said heating unit and having a supporting sleeve concentric with said unit.

10. A heater of the character described comprising a parabolic reflector, an approximately cylindrical heating unit having its axis coincident with the axis of said reflector, and means whereby said heating unit may be electrically connected with a standard lamp socket.

11. A heater of the character described comprising a fixture having means for providing a plural ty of circuits, and heating units and lighting units attached to said fixture and connected with the respective circuits.

12. A heater of the character described comprising a fixture having means for providing a plurality of circuits, a plurality of spaced apart heating units attached to said fixture, and an intermediate lighting unit also attached to said fixtu e, said heating units and said lighting unit being connected with the respective circuits.

13. A heater of the character described comprising a parabolic reflector, a heating unit, and means whereby both may be connected to a standard lamp socket, said reflector'and said heating unit being relatively adjustable to bring them into focus.

14. A. heater of the character described comprising a parabolic reflector, and an approximately cylindrical heating unit having its axis coincident with the axis 0 the reflector, said heating unit and said refl tor being relatively adjustable to bring them into focus. 7

In testimony whereof I have hereunto set my hand.
